(54) FIXING STRUCTURE OF RESOLVER ROTOR AND FIXING STRUCTURE OF ROTATION BODY FOR MOTOR


(57) A fixing structure of a resolver rotor includes: a rotation shaft (14, 114); and resolver rotors (31, 32, 131,132) that are inserted to an outer peripheral surface of the rotation shaft from the same side, wherein each of the resolver rotors includes claw portions (43, 143, 63) intermittently abutting against the rotation shaft along a circumferential direction of the rotation shaft, and wherein when viewed in a direction along a longitudinal direction of the rotation shaft, each of the resolver rotors is fixed to the rotation shaft such that a part of regions, in which claw portions of the resolver rotors inserted to the rotation shaft later abut against an outer peripheral surface of the rotation shaft, is disposed in a position different from regions in which the claw portions of the resolver rotor that is firstly inserted abuts against the outer peripheral surface of the rotation shaft.
